# MarkTimes vs SunAlly

The clearest difference is rating: MarkTimes at 5.0 against SunAlly's 4.3. MarkTimes also leads on review sentiment (100% vs 60%) and ratings volume (52 vs 9). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. MarkTimes sells 4 in-app purchases, starting at $0.99 per month and SunAlly sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

MarkTimes holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: MarkTimes has 52 ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 100% of MarkTimes's written reviews are positive against 60% of SunAlly's.

MarkTimes ships an update every 5 days, SunAlly weekly. The most recent releases landed on September 26, 2026 and August 21, 2026 respectively.
